Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a positioning device for grooving sheet metal. Background Technology

[0002] In the current sheet metal processing industry, the grooving process demands increasingly higher precision and efficiency. Traditional sheet metal grooving relies heavily on manual positioning, which is easily influenced by operator experience, resulting in large positioning deviations and low repeatability, leading to unstable grooving quality and high rework rates. While some existing positioning equipment achieves semi-automation, it suffers from insufficient flexibility in movement and adjustment, and cannot accurately adapt to different sheet metal specifications. Furthermore, the debris generated during processing is difficult to collect, increasing the manual cleaning burden and polluting the work environment, thus hindering the improvement of processing efficiency and workshop environmental quality. Therefore, there is an urgent need for a sheet metal grooving positioning device that offers precise positioning, flexible adjustment, and debris collection capabilities to address these industry pain points.

[0003] The existing patent document CNCN221968198UU discloses an automatic grooving device for EVA sheets with accurate positioning, belonging to the field of sheet processing technology. This automatic grooving device for EVA sheets with accurate positioning includes a device body, a grooving module mounted on the top of the device body, and an arc-shaped gripper slidably connected to the top of the device body. The arc-shaped gripper has a support assembly inside, including a hydraulic chamber. This automatic grooving device for EVA sheets with accurate positioning allows for clamping of arc-shaped sheets by moving the arc-shaped gripper; when clamping square sheets, moving the control lever downwards, in conjunction with the hydraulic chamber, baffle, elastic rod, transmission rod, barrier plate, square opening, and square support plate, allows for positioning and support of the square sheet. This means the device can position and clamp both square and arc-shaped sheets, improving the overall positioning and clamping effect of the device.

[0004] However, due to the lack of flexible adjustment measures for the grooving position during actual use, and the inconvenience in collecting and processing the debris generated during board processing, this device is not very convenient to use. Therefore, we propose a positioning device for board grooving, which solves the problems of difficult adjustment of the grooving position and inconvenient debris cleaning, improving the device's flexibility, convenience, and processing efficiency, and reducing the workload of workers. Utility Model Content

[0005] The purpose of this invention is to provide a positioning device for slotting sheet metal, which solves the problems of difficulty in adjusting the slotting position and inconvenience in cleaning up debris in existing devices.

[0006] To achieve the above objectives, this utility model provides a positioning device for slotting sheet metal, including a positioning platform, a rectangular groove on the top surface of the positioning platform, a material collection cavity inside the positioning platform, a guide plate with a slope of not less than 30 degrees on the bottom surface of the material collection cavity, and an adjustable positioning rod fixedly installed inside the rectangular groove. It also includes a lateral moving mechanism and a longitudinal moving mechanism. The lateral moving mechanism is fixed to the lower end of the longitudinal moving mechanism. The longitudinal moving mechanism includes a gantry and a movable crossbar. The upper inner wall of the gantry is provided with a longitudinal sliding groove. The two ends of the movable crossbar are longitudinally slidably connected to the longitudinal sliding groove. A longitudinal lead screw is vertically threaded through the middle of the movable crossbar and threadedly connected to it. The two ends of the longitudinal lead screw are rotatably connected to the inner wall of the gantry, and one end of the lead screw is fixedly connected to a first motor through a coupling.

[0007] The adjustable positioning rod includes an adjusting rod, on the top surface of which an inverted L-shaped plate is fixedly welded. The two ends of the inverted L-shaped plate are vertically inserted and threadedly connected to clamping screws. The top end of the clamping screw is fixedly provided with a horizontal handle, and its bottom end is rotatably connected to a positioning pressure block through a bearing seat.

[0008] The movable crossbar has connecting blocks fixedly installed at both ends. A transverse lead screw is rotatably installed on one side of the lower end of the two connecting blocks that are close to each other. One end of the transverse lead screw passes through the connecting block and is fixedly connected to a second motor through a coupling. The second motor is fixedly installed on the side of the connecting block away from the transverse lead screw.

[0009] The guide block is threaded to the outer side of the transverse lead screw. A limit rod is horizontally inserted and slidably connected to the upper end of the guide block. Both ends of the limit rod are fixedly connected to the connecting block. A horizontal plate is fixedly installed at the bottom end of the guide block. A hydraulic telescopic rod is fixedly installed on the bottom side of the horizontal plate. A grooving machine is fixedly installed at the bottom end of the hydraulic telescopic rod.

[0010] The gantry is fixedly mounted on the top of the positioning platform, the first motor is fixedly mounted on the upper outer wall of the gantry, and a PLC controller is embedded in the outer wall of the positioning platform. The PLC controller controls the opening and closing of the first motor, the second motor, the hydraulic telescopic rod, and the grooving machine.

[0011] The rectangular groove has a reference scale fixed on its top surface, a discharge port is opened on the bottom side of the positioning platform, the lower end of the guide plate is smoothly connected to the discharge port, a retaining strip is fixed on the outer wall of the discharge port, and a baffle plate is inserted inside the retaining strip.

[0012] This utility model discloses a positioning device for grooving sheet metal. A first motor drives a longitudinal lead screw to rotate, which in turn moves a movable crossbar along a longitudinal sliding groove to a set position. A second motor then drives a transverse lead screw to rotate, which in turn moves a guide block along a limiting rod to a set position. This allows the grooving machine to flexibly position itself to different areas of the sheet metal surface, eliminating the inconvenience of repeated manual sheet metal movement and improving processing efficiency. A material collection chamber with an inclined bottom is installed below the grooving machine. Combined with a discharge port and a baffle plate, waste generated during sheet metal processing can be collected and processed centrally, reducing the workload of operators and improving the environmental quality of the work area. Adjustable positioning rods and a reference scale on the positioning platform facilitate fixing the sheet metal in the designated position, thereby improving grooving accuracy and ensuring the best processing results.

[0016] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0017] The first embodiment of this application is as follows: Please see Figure 2 - Figure 4 This embodiment of a positioning device for slotting sheet metal includes a positioning platform 1. A rectangular groove 2 is formed on the top surface of the positioning platform 1. A material collection chamber 3 is formed inside the positioning platform 1. A guide plate 4 with a slope of not less than 30 degrees is provided on the bottom surface of the material collection chamber 3. An adjustable positioning rod 5 is fixedly installed inside the rectangular groove 2. The adjustable positioning rod 5 includes an adjusting rod 22. An inverted L-shaped plate 23 is fixedly welded to the top surface of the adjusting rod 22. Clamping screws 24 are vertically threaded through both ends of the inverted L-shaped plate 23 and connected to it. A horizontal handle 25 is fixedly provided at the top of the clamping screw 24, and a positioning pressure block 26 is rotatably connected to its bottom end via a bearing seat. A reference scale 27 is fixedly provided on the top surface of the rectangular groove 2. A discharge port 28 is formed on the bottom side of the positioning platform 1. The lower end of the guide plate 4 is smoothly connected to the discharge port 28. A retaining strip 29 is fixedly provided on the outer wall of the discharge port 28, and a baffle plate 30 is inserted inside the retaining strip 29.

[0018] The above method involves placing the sheet material on the positioning table 1 and adjusting its position using the reference scale 27 on the top surface of the rectangular groove 2. Then, by rotating the horizontal handle 25 of the clamping screw 24 in the adjustable positioning rod 5, the clamping screw 24 causes the positioning block 26 to move downwards. The inverted L-shaped plate 23 cooperates with the positioning block 26 to clamp the sheet material, preventing movement and displacement during processing and ensuring processing accuracy. Waste generated during the grooving process automatically falls into the rectangular groove 2 and then into the collection chamber 3. Guided by the guide plate 4 with a slope of not less than 30 degrees, it is collected at the discharge port 28. When waste needs to be cleaned, the retaining gate plate 30 inside the clamping strip 29 is pulled out to discharge the waste from the discharge port 28.

[0019] The second embodiment of this application is as follows: Please see Figure 1 - Figure 3Based on the first embodiment, the positioning device for grooving sheet metal in this embodiment further includes a transverse moving mechanism 6 and a longitudinal moving mechanism 7. The transverse moving mechanism 6 is fixed to the lower end of the longitudinal moving mechanism 7. The longitudinal moving mechanism 7 includes a gantry 8 and a movable crossbar 9. A longitudinal sliding groove 10 is provided on the inner wall of the upper end of the gantry 8. The two ends of the movable crossbar 9 are longitudinally slidably connected to the longitudinal sliding groove 10. A longitudinal lead screw 11 is vertically threaded through the middle of the movable crossbar 9 and threadedly connected to it. The two ends of the longitudinal lead screw 11 are rotatably connected to the inner wall of the gantry 8, and one end of the lead screw 11 is fixedly connected to a first motor 12 through a coupling. Connecting blocks 13 are fixedly provided at both ends of the movable crossbar 9. A transverse lead screw 14 is rotatably installed on one side of the lower ends of the two connecting blocks 13 that are close to each other. One end of the transverse lead screw 14 passes through the connecting block 13 and is fixedly connected to a second motor 15 through a coupling. The second motor 15 is fixedly installed on the side of the connecting block 13 away from the transverse lead screw 14. A guide block 16 is threaded onto the outer side of the transverse lead screw 14. A limit rod 17 is horizontally inserted and slidably connected to the upper end of the guide block 16. Both ends of the limit rod 17 are fixedly connected to the connecting block 13. A horizontal plate 18 is fixedly installed at the bottom of the guide block 16. A hydraulic telescopic rod 19 is fixedly installed on the bottom side of the horizontal plate 18. A grooving machine 20 is fixedly installed at the bottom of the hydraulic telescopic rod 19. The gantry 8 is fixedly set on the top of the positioning platform 1. The first motor 12 is fixedly installed on the upper outer wall of the gantry 8. A PLC controller 21 is embedded in the outer wall of the positioning platform 1.

[0020] Through the above scheme, the PLC controller 21 coordinates the actions of the horizontal moving mechanism 6 and the vertical moving mechanism 7. During vertical movement, the first motor 12 drives the vertical lead screw 11 to rotate, causing the movable crossbar 9 to slide longitudinally along the longitudinal sliding groove 10 of the gantry 8; during horizontal movement, the second motor 15 drives the horizontal lead screw 14 to rotate, causing the guide block 16 to slide laterally along the limit rod 17. By adjusting the position of the grooving machine 20 through horizontal and vertical movement, and with the plate fixed by the adjustable positioning rod 5 on the positioning table 1 and the reference scale 27, the hydraulic telescopic rod 19 pushes the grooving machine 20 down to groove, and the waste material enters the collection chamber 3 through the rectangular groove 2, is guided to the discharge port 28 by the guide plate 4, and can be discharged after being removed from the baffle plate 30.

[0021] Working principle : First, using the adjustable positioning rod 5 and reference scale, the material to be processed is placed at the designated position on the top surface of the positioning table 1, with one end of the material resting on the adjusting rod 22. Rotating the clamping screw 24 clockwise causes the positioning block 26 to move downwards, thus achieving the positioning and fixing effect of the material. Then, the PLC controller 21 activates the first motor 12, which drives the longitudinal lead screw 11 to rotate, thereby moving the movable crossbar 9 back and forth along the longitudinal sliding groove 10 to the set position. Next, the PLC controller 21 activates the second motor 15, which drives the transverse lead screw 14 to rotate, thereby moving the guide block 16 left and right along the limit rod 17 to the set position. Finally, the PLC controller 21 activates the hydraulic telescopic rod 19, causing the grooving machine 20 to move downwards to perform grooving processing on the material. This structure is simple to operate, can flexibly perform grooving processing on different areas of the material surface, and has high efficiency. Waste materials such as debris generated during processing automatically fall into the collection chamber 3 for collection. When the collection chamber 3 needs to be cleaned, the baffle plate 30 is pulled out upwards, and with the help of the inclined guide plate 4, the waste materials can be easily discharged from the equipment. It is very convenient to use, which not only reduces the workload of the workers, but also improves the environmental quality of the work area.

[0022] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
